Fishing device

ABSTRACT

Fishing device, such as a lure ( 1 ), in which there is a body ( 2 ), to the front end of which are attached means ( 3 ) for attaching a line ( 4 ) and at the rear end of which are winglets ( 11, 12 ) that rotate due to the force of the water flow. The winglets ( 11, 12 ) are mounted eccentrically on bearings on an essentially wire-like axle ( 9 ) to rotate in opposite directions and/or at different speeds. The winglets ( 11, 12 ) are essentially triangular, the bearing point being essentially at, or in the immediate vicinity of one point of the triangle.

The present invention relates to a fishing device and more specifically to a device, which can be most nearly be referred to as a lure.

Though fishing is a sport that demands skill, skills being naturally properties of the fisher, much of fishing's result depends, however, on the domain of fishing tackle.

When a lure is used, no matter whether in trolling or spinning, the lure, which can have quite diverse properties, is attached to a line. A so-called spinner is a metallic, concave piece that rotates in the water around a wire-like axle and is of a colouring and size that are intended to attract a specific species of fish, or fish in general. The hooks attached to the rear of the spinner are intended to catch in the mouth of a fish seizing the spinner. The spinner rotates evenly, depending on the speed at which it is pulled.

A wobbler-type lure on the other hand is a larger type of lure, with an appearance and size that seek to imitate a small fish. A wobbler can be equipped with various plate-like guides, which are intended to keep the lure, which is often made of a material lighter than water, under the surface, though the guides can also be intended to affect the lure's swimming properties. A wobbler can also be equipped with an articulated joint. It is difficult to use guides, such as a so-called nose plate, to guide a wobbler if it has a significant weight. As wobblers are therefore often relatively light, their throwing distance in spinning, on the other hand, is modest.

A problem with the fishing properties in all known solutions is that the fishing part moves unnaturally from the viewpoint of the predatory instinct of a normal fish. In other words, the lure does not move in a manner that would arouse the predatory instincts of a predatory fish, because the motion patterns do not sufficiently resemble the patterns of motion of a prey fish.

A numerous group of various types of lure solutions, in which rotating parts are used, are also known from the prior art. Most of the various types of rotating winglets are intended to attract fish, though in some applications it is also stated that the intention is to stabilize the motion of the lure.

Some known solutions contain two rotating propeller parts. US patent application 2004/0049970 discloses two consecutive propellers, which rotate due to the water flow and which rotate in opposite directions due to their different curvature. The blades are symmetrical relative to the axis of their bearings. The patent discloses that the said blades cause motion, because the water flow is uneven, relative to the body of the lure.

The present invention is intended to create a fishing device, specifically a lure-type fishing device, with the aid of which fish can be caught more effectively than with existing devices, due precisely to the apparently natural movements of the device. The intention is particularly to create a fishing device, the movements of which are no longer random, but are compelled to be of a desired type.

These and other benefits and advantages of the invention are achieved in the manner described as characteristic in the accompanying claims.

In the following, the invention is described in greater detail with reference to the accompanying drawings, in which one embodiment of the invention is shown schematically.

Thus, FIG. 1 shows a side view of a lure according to the invention;

FIG. 2, for its part, shows the arrangement of the winglets of the lure, with its movements seen from directly behind, relative to the direction of travel of the lure.

Thus, FIG. 1 shows a lure-type fishing device 1, in which there is a suitably shaped body 2, possibly resembling a small fish or other bait, which can be made from wood, plastic, or any other material whatever that is conventionally used for manufacturing lures. The body part 2 can be equipped with a coating, which can be suitably coloured, as is the manner in this field, and weights or other auxiliary components, such as guide plates, can be added to it, if necessary.

In the usual manner, in the front part of the body there is a suitable loop 3, to which a line 4 for pulling the lure is attached. Depending on the weight distribution of the body, the line 4 may be attached in different parts of the body, however, normally in the very front part of the same. A sufficient number of hooks 5, 6 are added for catching a fish. The hooks can be attached permanently or movably. One conventional form of movable attachment is to attach to the lure a loop made of wire-like metal, to which the loop of the hook is secured. Of course, various types of spacer pieces can also be used, if desired.

In the rear part of the lure, relative to its direction of travel, is a loop 7 to which a wire-like axle 9 is attached in a freely articulated manner, for example attached to the loop 7 with the aid of a loop 10 at the end of the axle 9. At the rear end of the axle, there is also a loop 8, to which a hook 6 can be attached, if such is used. Any kind of stopper whatever can be used in place of the loop 8, if there is no need to attach a hook.

The winglets 11 and 12 shown are an essential feature of the invention. The winglets 11 and 12 each have two sides or ends, a proximal end A and a distal end B. These winglets are mounted on bearings eccentrically, or off center, on the axle 9. In particular, the winglets are mounted on bearings on one end, the proximal end A of the winglet 11/12, or close to it. Distal end B of each winglet 11 and 12 extends outwardly from the axle 9. The term bearing usually refers to a hole drilled through the winglet. Each winglet 11/12 has a base 13 disposed at the proximal end A which is longitudinally aligned with the axle 9 and a pitched blade 14 extending from the base 13 to the distal end B of the winglet 11/12. The winglets can be separated from each other or their surroundings by means of suitable beads or bushings.

The winglets are shaped like propellers, so that, when the lure is pulled, the water resistance causes the winglets to rotate in opposite directions around the axle 9.

FIG. 2 shows the movements of the winglets as a series of images. The winglets are approximately shaped as quarter circles, though this is in no way essential.

In the initial situation, the winglets 11,12 are essentially opposite to each other and relative to the axle 9. The water flow causes the winglets to rotate towards each other, forming first a semicircle when seen from behind, which then narrows to become a quarter circle and then widens to become two opposing quarter circles.

What then happens when the lure is pulled? The rotational movement of the winglets mounted in bearings on the axle causes the water resistance to vary greatly and rapidly, causing strong pulses pushing sidewards, so that the axle 9 with the winglets seeks to turn in one direction while at the same time the rear end of the lure seeks to turn correspondingly in the opposite direction. The motion is surprisingly like the rapid movements of the tail of a small fish, which naturally leads to the excellent fishing properties of a lure of this type.

According to the image series shown in FIG. 2, each winglet 11 and 12 has made a complete circle, when the rear part of the lure has caused one swing to the left and one swing to the right. The figure also shows that, in the position in the initial situation, the winglets are symmetrical relative to the axle 9, and in this position cause practically no lateral movements in the body. In all other positions, the effects are asymmetrical and tend to swing the body to one side or the other.

The movements induced in the lure are mainly lateral. Though a certain force also tends to act on the body 2 vertically, the weight of the body keeps this movement quite small, as the lifting force would have to be clearly greater, if a significant vertical movement were to take place. The weight of the body 2 can be adjusted by material selections and, if necessary, by adding weights.

Reference has been made above to essentially quarter-circle-shaped winglets. However, the size of the winglets is not very critical. In fact, by using assemblies with different winglets of varying size, different kinds of swimming property will be achieved. The properties can also be altered by altering the shape of the winglets, for example, by changing the blade pitch. The rotation speed will then naturally change. Obviously the rotation speed of the winglets must not exceed a certain threshold, as higher rotation speeds will probably prevent the lure body from being able to move as desired.

The manufacturing material of the winglets 11/12 is especially plastic, which easily worked. The base part 13 of the winglet around the bearing wire 9 in the longitudinal direction must be sufficient for the winglet to remain in the desired position. Otherwise, the winglets can be of a quite thin material. Of course, the winglets can easily be made from sheet metal.

The size of the lure or the winglets belonging to it can vary considerably, depending on the fish it is intended to catch, as well as on many other factors. It is also possible to make the lure relatively heavy, thus permitting long throws when spinning. The size of the winglets can be proportional to the weight of the lure.

The fishing device according to the invention permits lure fishing in quite shallow waters, because the winglets cause a specific upward force, which naturally tends to lift the lure. It is easy to alter the swimming depth of the device according to the invention by changing the pulling speed.

The above only describes a construction, in which the winglets 11 and 12 rotate in opposite directions. However, though this is certainly quite a good alternative it is not the only one. The winglets can also rotate in the same direction, but then they must rotate at different speeds. A speed difference can be easily realized in at least two obvious ways, i.e. by using different pitches in the winglets and/or by altering their size. The important thing is that, when the lure is pulled, the water flow alternates between a freer and a more restricted flow, so that this variation causes varying lateral forces on the axle 9 and the rear end of the lure. The result is a lure motion resembling the swimming movements of a small fish.

Similarly, the above only describes an alternative, in which the winglets 11 and 12 are located at the trailing end of the lure relative to the direction of travel. Nothing, however, prevents the winglets being located at the front of the lure in the direction of travel. A logical construction would then be one in which the axle 9 runs straight ahead and the line is attached to a loop or similar attachment point at the end of the axle. As there is a constant pull on the lure from the line, this would appear to equalize to some extent the movements caused by the winglets, though the movements are essentially the same as when the winglets are located at the rear of the lure. It can even be assumed that the winglets cause clear movements in the rear end of the lure too, especially if the body is made relatively light.
